Types of Tanks:Range Boiler small hot-water tank; 12 24/6
longStorage Tank large hot-water tank; 24 54/15 long
STORAGE TANK/WATER HEATING DEVICESRange Boiler
Hot-Water Distribution Systems convey heated water storage unit
to fixtures Three Types of Installations:1 Upfeed and Gravity
Return small residential/industrial installations; constant
circulation of hot water within the piping arrangement. 2 Overhead
Feed and Gravity Return System buildings of extreme height; in the
closed system of piping water rises when heated. As it reach the
high point of the system, gravity return it to the storage unit.
Pump Circuit System circulation of hot water to by means of
mechanical device; larger buildings
The Indirect and Direct Plumbing System1 Indirect - has only the
amount of pressure from the gravity created from the cold water
storage tank2 Direct - has the same cold water pressure that is
available from the mains water in the street.
